Performance is correct, it is more powerful than a NAS (debits read / write around 110MB / s, enough to saturate a gigabit link), however it must be remembered that this is a micro server, it is not for the big virtualization :)
Level connections, the use of SATA and the presence of numerous USB ports (one internal) make an inexpensive machine complete and scalable.
This machine also supports DDR3 non-ECC, one can easily find 8GB non-ECC kits for thirty euros :) (by cons attention mixture ECC / non-ECC prohibited).
